A TWO STEP METHOD OF MAKING A NITROGEN-ENRICHED SWEETNED FEED FOR RUMINANTS COMPRISING FIRST REACTING AMMONIA WITH A SUGAR-CONTAINING SIRUP AT A TEMPERATURE BETWEEN 140* AND 220*F. UTILIZING AMMONIA IN AMOUNT BETWEEN 2 AND 5.5% OF THE DRY DUBSTANCE WEIGHT OF THE SIRUP AND MAINTAINING THE PH OF THE SIRUP DURING THE FIRST STEP BETWEEN 4.0 AND 7.5 PH BY THE ADDITION OF ACIDIC MATERIAL DURING THE FIRST STEP THEREBY INCREASING THE PROTEIN EQUIVAENT OF THE SIRUP BETWEEN 5 AND 30%, SECONDLY, MIXING THE TREATED SIRUP WITH PULVERULENT FEED SOLIDS, DRYING THE MIXTURE THEREOF WHILE TO HEAT AT A TEMPERATURE BELOW 220*F. UNTIL THE MOISTURE CONTENT IS REDUCED TO BETWEEN 1 AND 5% AND THEN TERMINATING THE AMMONIATION REACTION BY COOLING THE MIXTURE TO A TEMPERATURE SUBSTANTIALLY BELOW 140*F.
